Make a Book with a Secret Compartment 📕

I show how to make a book safe that can be used to hide small items. 📚 Book safes are an age-old way to stash one's treasures--the key to a safe, a private document, a flask, a gun. And you can use them while traveling to hide your iPod, backup cash, or other valuables from would-be thieves. A hollowed-out book is a clever place to hide valuables. There are many companies that have book safes on the market, but why buy something that can be easily made at home with a bit of time and patience. You get to choose the book and set the depth of the safe. It a great place to hide your valuables or impress your friends.

Hi! i am making one of these for my friend and i glued about 15 pages or so in the front so i could keep the front page art but now there is a huge crease that makes it almost impossible for the book to stay closed on its own. Is there any way I can get rid of the crease? Or is there an easy way to remove the glue to reglue it? PLEASE HELP!
